The Australian Transport Safety Bureau has opened an investigation into air traffic control at Sydney Airport after a Virgin Australia Boeing 737 was cleared for takeoff while a Qantas 737 was cleared to cross the same runway, forcing the Virgin flight to abort.

This incident is the third near-miss at Sydney Airport in three weeks, underscoring broader staffing shortages affecting airport operations.

Earlier close calls involved a Jetstar A320 and a Qatar Airways 777 tow-related near collision, in addition to a July 27 near miss between a QantasLink and a Qantas plane on the tarmac.

The investigation has not yet produced definitive outcomes, with further information expected as the ATSB continues the inquiry.

Investigators are examining whether training or supervision in the control tower at the time played any role, though details remain unclear.

The ATSB noted a reporting delay from Sunday to Monday lunchtime, breaching mandatory reporting requirements and to be explored during the inquiry; the delay may be linked to ongoing training.

Industry voices say Airservices is structurally reliant on overtime, with controllers often working extended stretches, contributing to fatigue concerns.

Airservices Australia chief executive acknowledged the organization has been slow to hire new air traffic controllers.

Roster management and staffing challenges persisted for three consecutive days, amplifying operational strain at the hub.

Federal Transport Minister described disruptions as unacceptable but said Airservices is taking steps, including short-term rostering changes and plans to add 95 controllers by year-end.

The NSW Premier emphasized the need to recruit more specialized air traffic personnel and referenced plans for a new airport to support capacity and safety.

Industry stakeholders warn of ongoing staffing problems at ATC towers nationwide, signaling persistent disruption and safety concerns for airlines and passengers.
